Problem with Data.j2d

[rionaam]

I was playing JJ2:TSF normally when I closed it. Next time I tried to open it an error message appeared saying:
"The library file 'Data.j2d' is incomplete, corrupt or of an unknown version."
I don't remember doing anything that could modify it. So, if anyone knows how to fix it, and why it happened (so I make sure it won't occur again) I'd be very grateful.

It means what it says. Try replacing it with a clean data.j2d.

Where should I get it? Should I reinstall the game?

Reinstalling into the same folder is always quicker than asking for help on jcf

Yes, I solved the problem. I installed it into another folder, then copied the data.j2d into the original folder and deleted the new one.
